Fostex MR 8 HD\CD adding treble and bass?
It APPEARS that the MR8 does NOT include the ability to EQ. They have delay effects and the like built in, but no EQ.
To answer your question then, you would need to have an EXTERNAL EQ unit and loop the vocal through that unit to do EQ to do it right.
When mastering, the "powerful/natural/and bright would be filters that will emphasize the bass (powerful) or the treble (bright) but these are really not EQ's and you can ONLY choose one at a time.
